杭电入门级水题，应该是大部分人在杭电做的第一道题吧，对于格式的掌握，也是从这里开始的，用三种方法：

c版本：

#include<stdio.h>
int main(){
    int a,b;
    while(scanf("%d%d",&a,&b )!=EOF)
    printf("%d
",a+b);
}

c++版本：

#include<iostream>
using namespace std;
int main()
{
    int a,b;
    while(cin>>a>>b)
        cout<<a+b<<endl;
    return 0;
}

java版本：

import java.io.*;
import java.util.*;
class Main {                                           //一定要是Main
    public static void main(String[] args) {
        Scanner cin = new Scanner(new BufferedInputStream(System.in));
         int n,m;
        while(cin.hasNext())
        { 
             n = cin.nextInt();
             m = cin.nextInt();       
            System.out.println(n+m);
        }
    }
}

至与三种方法的大小，自己提交过后一比就知道了。
